At present, the spinning is loved by people as an indoor fitness apparatus. The spinning is provided with a resistance adjusting knob, and a user operates the resistance adjusting knob to further control the transmission mechanism connected with the spinning to move, so that the transmission mechanism controls the depth of the magnet, which cuts into the flywheel, to achieve the purpose of controlling the riding resistance. In addition, in order to facilitate a user to monitor motion data in a motion process in real time, for example, riding resistance, a bicycle flywheel rotation speed and the like, an electric control meter is usually installed on a head of the spinning bicycle, wherein the electric control meter is electrically connected with other parts on the bicycle through a wire, so that the electric control meter can acquire the motion data of the user in the riding process through the other parts and further display the motion data on the electric control meter.
In the prior art, in order to obtain resistance during riding, a sliding potentiometer is generally connected to a transmission mechanism connected with a resistance adjusting knob. When a user rotates the resistance adjusting knob, the resistance adjusting knob drives the transmission mechanism connected with the resistance adjusting knob to move, and then the adjusting part of the sliding potentiometer connected with the transmission mechanism changes the output physical parameters of the circuit where the sliding potentiometer is located, and then the riding resistance of the current user is obtained according to the output physical parameters.

Compare the change that drives the slip potentiometre through the motion of monitoring drive mechanism among the prior art, because the motion change of drive mechanism itself is very little for lead to through the lower technical scheme of the slip potentiometre change of monitoring finally definite resistance precision itself, the rotation angle of knob is changeed and is acquireed in this application, and the monitoring is more accurate, makes the resistance that finally obtains also more accurate. In addition, compare the resistance acquisition mode among the prior art, can carry out data transmission (for example, bluetooth transmission mode) through wireless mode between intelligent knob, the flywheel in this embodiment, and then reduced the outside wire on the vehicle and connected, avoid damaging and can't obtain the resistance because of the outside wire, influence the condition that the user used and experienced.
